0.05 ~ 1 Hz范围内地震观测的引力波随机背景上限

Upper Limit on a Stochastic Background of Gravitational Waves from Seismic Measurements in the Range 0.05 Hz to 1 Hz

Michael Coughlin, Jan Harms

摘要:

在本文中,我们提出了一个上限的$Ω_{\rm GW}<1.2\times 10^{8}$的各向同性随机引力波(GW)的背景下集成了一年的频率范围为0.05 Hz - 1 Hz,提高了约9个数量级的高精度实验室实验的电流上限。这个极限是通过F. J. Dyson在40多年前描述的自由表面效应,利用地球本身对GWs的响应获得的。反应是由一个全球网络的宽带地震仪选择,以最大限度地提高灵敏度。

英文摘要:

In this paper, we present an upper limit of $Ω_{\rm GW}<1.2\times 10^{8}$ on an isotropic stochastic gravitational-wave (GW) background integrated over a year in the frequency range 0.05 Hz - 1 Hz, which improves current upper limits from high-precision laboratory experiments by about 9 orders of magnitude. The limit is obtained using the response of Earth itself to GWs via a free-surface effect described more than 40 years ago by F.J. Dyson. The response was measured by a global network of broadband seismometers selected to maximize the sensitivity.
